About this entry

67% of key specs known. Missing: movement, lug width, weight, hardening, AR coating.

The bronze version of the Torsk-Diver Professional, the 43mm follow-up to the 2019 Torsk-Diver, named after the USS Torsk (SS-423) museum submarine. The brand's spec table: 43mm, "13.6mm Thickness", 50mm lug-to-lug, automatic MD-1 with 40 hours of power reserve, CuSn8 bronze, textured sunburst dial, double-domed sapphire crystal and a sapphire bezel insert; the MD-1 is "regulated in 4 positions to +-8 sec/day", and BGW9 Super-LumiNova covers the hour markers, hands, chapter ring and bezel. The brand says the bronze version "is limited to only 423 timepieces". aBlogtoWatch's review adds 300m water resistance, a 120-click bezel with a colour-matched domed sapphire insert, a screw-down crown at 2 o'clock with a crown guard, a sapphire display caseback, and the fitted FKM strap without quick-release pins (the steel version comes on a bracelet). Lug width, AR coating, bezel direction and weight aren't published. Movement: the MD-1 is made by Maryland Watch Works in Hagerstown, MD; Watch Clicker calls it "a clone of the ETA 2824" and aBlogtoWatch says it is "based on the ETA 2824" at 28,800 vph, but neither names the base caliber or its maker, so only the type is recorded. The Bitcoin edition ("Torsk-Diver Professional - Bronze Bitcoin Edition", 50 numbered pieces, issued with an NFT) shares the case and movement and has a rose-gold-coated meteorite dial and bezel insert; it was imported as a separate draft and merged here, and was listed in September 2023, before the regular colourways (January 2024). The brand doesn't say whether the Bitcoin pieces count toward the 423. Every version was sold out on 2026-10-25.
